AUTONOMOUS MODE FIXED STATION INTERFACE FOR LEGACY BASE STATION EQUIPMENT

摘要

An interface device for provisioning Internet Protocol (IP) communications to be established for base station equipment that employ proprietary device specific protocols. A fixed station interface (FSI) translates between a V.24 High-Level-Data-Link Control (HDLC) protocols used for external data connections on base station equipment to a Voice-Over-Internet-Protocol (VOIP) open-standard protocol. Upon being deployed in First Responder communications networks (that use legacy base station equipment), the FSI provisions for the retention of existing installed base station equipment while providing a low cost solution to support VOIP communications interconnectivity and reliability, thereby enhancing the effectiveness and safety of the First Responder systems.
